Pneumoconiosis is a type of occupational disease. Clinically, the diagnosis can generally be made based on the duration of exposure and the concentration of dust particles, which may cause different clinical symptoms in patients. In the early stage of pneumoconiosis, symptoms are generally not very obvious. Some patients may only experience some shortness of breath, especially after physical activity, and other symptoms like coughing and expectorating phlegm may not be prominent. Therefore, the diagnosis of stage one pneumoconiosis mainly relies on the patient's medical history and related auxiliary examinations. Therefore, for pneumoconiosis, if there is a suspected diagnosis, it is recommended to leave the dusty environment as soon as possible to avoid further exacerbation of the condition.
